急性中毒是儿科常见的急重症。由于毒物种类、中毒途径、中毒程度的不同,因此病情较复杂,体液紊乱的情况也各异。轻者可无体液紊乱,也不需输液,重者常伴水、电解质和酸碱平衡紊乱,有时可同时有多种紊乱,甚至危及生命。即使无体液紊乱,也常需输液治疗。有时因治疗失误引起医源性体液紊乱。严重中毒常伴有休克、脑水肿、肾功能衰竭或心力衰竭等严重并发症,使液体疗法更加复杂。以上情况决定了液体疗法在小儿急性中毒抢救中的重要作用,若处理不当或不及时,可引起严重后果。处理时必须具体 Acute poisoning is a common pediatric severe illness. Due to the type of poison, poisoning pathways, different degrees of poisoning, so the condition is more complex, body fluid disorders are also different. Light body fluids can be no disorder, no infusion, often with severe water, electrolyte and acid-base balance disorders, and sometimes there may be a variety of disorders, and even life-threatening. Even without body fluid disorders, often require infusion therapy. Idiopathic humoral disturbances sometimes result from treatment errors. Serious poisoning is often accompanied by severe complications such as shock, cerebral edema, renal failure or heart failure, making fluid therapy more complicated. The above situation determines the important role of liquid therapy in the rescue of acute poisoning in children. If handled improperly or not, it may cause serious consequences. Processing must be specific
